Interfacial shear transfer of RC beams strengthened by bonded composite plates

In this paper an analytical method is proposed to predict the distributions of interfacial shear stress in concrete beams strengthened by composite plates. Non-linear behaviour of concrete under compression is considered in the analysis. The solutions show significant shear stress concentration near...

Description
Summary:In this paper an analytical method is proposed to predict the distributions of interfacial shear stress in concrete beams strengthened by composite plates. Non-linear behaviour of concrete under compression is considered in the analysis. The solutions show significant shear stress concentration near the cut-off end of plates. A parametrical study is carried out to show the effects of some design variables, e.g., thickness of adhesive layer, material properties and the distance from support to cut-off end of bonded plates.
